Matte Black Diver Watch Bezel and Case with Empty Face

A detailed, top-down view of a matte black watch case and rotating bezel, featuring a rugged, slightly textured finish. The bezel is marked with numbers (10, 20, 30, 40, 50) and minute indicators, surrounding an empty, dark circular watch face.
